Upon following MissKiller’s guide to change your forum name I sumbled upon a hickup, When you click “Save” after you enterd a profile name, you get a white page (same url) and your name will not change.
I tried to eddit the url
forums.dirtybomb.nexon.net/profile/username/charismaticSavant? to replace charismaticSavant with the prefered username, with no results.
